There's no clean way to do it, but you could do it with a macro that takes
IP_OFFSET_WIDTH as an argument, stringifies it (you can only stringify
arguments to a macro, not arbitrary stuff), and concatenates it with the stuff
before it and after it in the string:

    http://gcc.gnu.org/onlinedocs/cpp/Stringification.html

(the fact that it's at gcc.gnu.org nonwithstanding, it's a part of standard C,
not a GCCism).

(Also, you probably don't want to assign a bug to yourself unless you have
commit access to the Wireshark repository; somebody with that access is needed
to check the fix in, and, unless they've CCed themselves on the bug, they won't
see the changes.)
